What is electrostatic force?
Correct answer: B. Conservative
- A. Non-conservative
- B. Conservative
- C. It depends on the shape of the charge
- D. None of these options are correct
Explanation
The electrostatic, or Coulomb's, force is conservative, which means that the work done on q is independent of the path taken. This is exactly analogous to the gravitational force. When a force is conservative, it is possible to define the potential energy associated with the force.

About Coulomb's Law
Coulomb's law gives the electrostatic force between two point charges in terms of their magnitudes, separation and the medium between them. Questions involve attraction and repulsion, the inverse square relationship, superposition of forces and vector direction, which must not be confused with the electric field produced by a charge.
